How to authenticate to ML Classic from HTTP Request in Flow

Question

Hi - Hoping someone can help

Keep getting 401 error and cannot authenticate to a published Azure ML experiment using a Post in HTTP action within Flow

Guessing you use Basic authentication and supplied creds in action (as shown in the screenshot attached) but keep getting 401 error

See attached image of HTTP Post - anyone know how to authenticate so I can call Azure ML if created from flow?

I know it is possible but how???

Thx!

Stumped as I cannot find any documentation how to do it anywhere

Thx!

@Dave Chennault I do not have experience using flow but I think in this case the authentication bearer token is not passed along with the headers. I have an old endpoint of the classic studio that is still running and the steps to use the endpoint through REST can be obtained by clicking the REQUEST/RESPONSE link of the endpoint page from the studio.

I used postman to call the endpoint using the authorization method mentioned i.e Bearer token with the key mentioned in the endpoints page. Header value of Content-Type:application/json

I hope this helps!!
